BOOKBINDER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed April 22, 1907. S i O- 369,638.

To all whom it may concern:

Be it known that I, DON H. YORK, a citizen of the United States, residing at New York, in the county of New York and Slate of New York, have invented certain new and useful Improvements in Bookbinders, of which the following is a specification.

The present invention relates to means for securing leaves, papers, cards, pictures and like matter in book form, the purpose being to supply a binder that may be applied by the average person and which is cheap and readily conformable to a book of bound matter to admit of the same being opened out flat for convenience of reference and handling.

In the preferable form, the binder is elastic so as to retain the bound elements in position and prevent their sagging and to admit of the book opening flat at any place, the binder stretching to accommodate itself to the increased distance circumscribed thereby when the book is opened Jlat.

.For a full description of the invention and the merits thereof and' also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings. i

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a perspective view of a book having its leaves or elements bound in accordance with this invention. Fig. 2 is a transverse section of the book on the line 2*2 of Fig. 1. Fig. 3 is a similar view to Fig. 2 of a modification, the binder being solid instead of tubular. Fig. 4 is a perspective view of. a tubular binder. Fig. 5 is a perspective view of a solid binder. Fig. 6 is a perspective view of a binder having flattened end portions and an intermediate rounded portion. Fig. 7 is a perspective view of a portion of a book show ing the application of the form of binder illustrated in in Fig. 6. Fig. 8 is a perspective view of a binder similar in construction to Fig. 6 having the intermediate rounded portion made tubular. Fig. 9 is a detail view of the form of binder shown in Figs. l and 5 bent into circular form and having its ends cemented.

(.orresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The binder may be of any length but it is essential that the same be.elastic and that the portion adapted to engage with the leaves or elements to be bound, be of rounded form in cross section to minimize the wear upon the leaves or bound elements and prevent the binder cutting through the same which would be liable to occur if it presented sharp corners. Moreover, the rounded form enables the openings in the leaves or elements to be bound to be formed by a punch, the rounded form of the openings preventing the binder tearing therethrough. The binder may be of any length and may be solid as shown in Figs. 5 and 6, or tubular as indicated in Figs. 4 and 8.

In order that the binder when in position may be of uniform diameter throughout its length, and furthermore that a maximum amount of surface may be presented for receiving the cement material, the ends of the binder are scar-fed. The binder is constructed of rubber and maybe of any diameter length or cross sectional outline. It is contemplated to provide the binder in various sizes for different articles, and the size and weight of the completed book. While a flexible binder is contemplated, nevertheless, the best results are attained by an elastic binder, the latter preventing the leaves from sagging in the cover and admitting of the book opening flat at any point. These results are not attainable by the use of a flexible binder because if made sufficiently large to admit of the book opening flat, the leaves or elements are adapted to sag or have play'in the cover, or if made of a size to hold the leaves and cover from longitudinal movement, the

book cannot be opened flat without placing the binder under such tension as to endanger tearing the leaves, or to prevent the free turning of the same. The tubular form is preferable to the solid form because of lightness and the adaptability of the portions of the binder adjacent to the cover to flatten when a number of books are placed side by side or one upon the other. Moreover, for the same amount of material, the tubular form of binder may be of larger cross sectional area which is of advantage within certain limits in order to prevent the leaves or elements from tearing out, this tendency increasing as the diameter of the binder decreases.

The binder 1, shown in Fig. 4 is substantially the same in appearance as the binder 1 shown in Fig. 5, the only difference being that the one is tubular and the other solid. The binder shown in Fig. 6 coinprises flattened end portions 2 and an intermediate rounded portion 3, and the latter may be solid or tubular, the latter being indicated in Fig. 8. Flattened ends 2 are scarfed so as to form a neat and uniform joint when cemented. This form of binder is preferred for large books as it enables the rounded portion 3 to be of comparatively large diameter, whereas the exposed portion of the binder is somewhat flat to admit of the books being placed close together either in upright or horizontal position.

The matter to be bound in book form for future ready reference after being classified and arranged according to system or otherwise, is placed in a pile either with or without a cover, and openings are punched a short distance from one edge corresponding to the back, and a binder is passed through each opening and the end portions of the binder brought together and secured because of the elastic nature of the binder which permits it to give to any tension coming thereon, While at the same time permitting the leaves or bound elements to turn freely in either direction.

Having thus described the invention, what is claimed as new is:

1. A binder for leaves comprising a ring of flexible material passed through openings in the leaves, the said ring being formed of a strip of flexible material having the ends thereof scar-fed and connected by an adhesive.

2. binder for leaves comprising a tubular ring of ilexi l l l 1 l l l ble material passed through openings in the leaves, the said ring being formed of a tubular strip of flexible material having the ends thereof scar-fed and connected by an adhesive.

3. A binder for leaves comprising a ring of flexible and elastic material passed through openings in the leaves, the s-rid ring being formed of an elastic strip having the ends thereof scari'ed and connected by an adhesive.

4. A binder for leaves comprising a ring of flexible and elastic material passed through the openings in the leaves and formed of a strip having the ends thereof connected l to each other.

In testimony whereof I aflix my signature in presence, of

two witnesses.
